I didn't add that (yet), looking at the code I notice there are two
commands

(d-PutMidi value)
and 
(d-OutputMidi value)
the second of these directly outputs the MIDI event value to the MIDI
out, the first does something trickier:
        1) it turns off any MIDI filter
        2) simulates the arrival of the value as if it came from the MIDI in
device
        3) turns back on any MIDI filter that was active.
